  • the magnetic encoder 18 responds to rotation of the flux lines F passing there through by outputting a signal or signals that may be indicative of the direction, speed, and/or degree of rotation of the flux lines F passing there through and, therefore, indicative of the direction, speed, and/or degree of rotation of the knob 12.
